Blue Valentine generated a great deal of buzz when it premiered at Sundance earlier this year and has screened well at Cannes and Toronto as well. The two leads, Ryan Gosling and Michelle Williams, have especially been highlighted in reviews as potential Oscar contenders. With a limited release approaching in December, the Weinstein Company has released a new trailer for the film. While the film’s story of a crumbling relationship is simply and effectively portrayed in the trailer, what has garnered equal attention is the rating Blue Valentine has received from the MPAA.

Apparently, the film has been slapped with an NC-17, causing many to speculate what content led to the rating. According to Deadline, the NC-17 stems from a scene in which the leads spend a drunken night in a hotel room. Things get out of hand when one person wants to have sex and the other does not. From what I gather, people who have seen the film are somewhat puzzled by the decision as there is little nudity and no violence featured within the scene in question. While an NC-17 can be a challenge to overcome, it could also generate some additional publicity for the film as well. There’s no word yet on whether the Weinstein Company plans on appealing the rating, but I would think they’d try. For now, watch the trailer after the jump and let us know what you think of the film and its current rating debacle.
